The Limay River is an important river in the northwestern Argentine Patagonia (the region of Comahue ). It originates at the eastern end of the Nahuel Huapi Lake and flows in a meandering path for about 380 kilometres (240 mi), collecting the waters of several tributaries , such as the Traful River , the Pichileufú and the Collón Curá. It then meets the Neuquén River and together they become the Río Negro . At this confluence lies the city of Neuquén .
31-491: The river serves as natural border between the provinces of Río Negro and Neuquén . Its deep waters are clear, and carry a large flow, 700 cubic metres per second (25,000 cu ft/s) on average. Its drainage basin has an area of 61,723 square kilometres (23,831 sq mi) and includes almost all the rivers and streams of the Atlantic basin in the region, as well as an extensive network of lakes. The waters of

The valleys of La Pampa, known as the transverse valleys ( Spanish : valles transversales ) are NE-SW oriented, with breadths of various kilometers and lengths of tens of kilometers. Some of the valleys host very large fossil inland dunes . Formerly functioning as windfunnels for sand at present these valleys are an ecotone region between the Dry and Humid Pampas . While mostly flat,

La Pampa is home to hundreds of oil and gas wells, as well as deposits of sodium chloride, sodium sulfate, and copper. Tourism is an underdeveloped activity, however. Visitors start at Santa Rosa and reach Lihué Calel National Park , Parque Luro Provincial Reserve or visit one of
155-509: A federal system . During the War of Independence the main cities and their surrounding countryside became provinces though the intervention of their cabildos .

After seceding for a decade, Buenos Aires Province accepted

Buenos Aires City itself is divided into communes ( comuna ) and non-official neighbourhoods ( barrios ). Provinces hold all the power that they chose not to delegate to
279-515: Is one of the most important factors that influence the climate on a regional scale. During summer, the South Atlantic High is displaced to the southeast, which brings hot and humid air masses from the north and northeast. The South Pacific High in summer is responsible for bringing cooler air masses from the southwest which when these two contrasting air masses meet lead to precipitation occurring. In contrast, winters are dry due to
310-573: The Colorado ("Red River") on the border with the Province of Río Negro , and the Salado ("Salty River") crossing it. The Salado's level has been dropping, as its tributaries in the Province of Mendoza are diverted for irrigation .

Plentiful rainbow trout and brown trout , from 6 to 28 inches (and larger), live in the river. Various islands in the floodplains of the lower course of the river have been urbanized. The origin of the word comes from the Mapuche indians and it means, crystalline, that you could see to

The construction of the successive dams and reservoirs has reduced the length of

#1732765684847682-543: The northward displacement of the South Atlantic high and the topographic barrier of the Andes north of 40 S which prevents frontal systems that bring precipitation from reaching the province. Any winds from the southwest during winter bring in cold and dry weather since most of the precipitation and humidity are released in the Andes. As such, most of the precipitation occurs during summer. Mean annual temperatures in
